The invention relates to railway crossings of means whereby the'breaksin the tracks in the. crossing that cause a poundmg and eventualcrystallization, of therails and; chipping theccrossing: and providing arotary tread member, adapted to form acontinuationwof either of therails where crossed, and providinga means' wherebyisaid tread membersare7 moved into proper position toform, a con- 'tinuation of the tread ofthe rails forming the tracks on which the; cars: are, approaching thecrossing," means beingalsoprovided and 0p eratedibythe wheelsiof thecars to automatically move the tread member into proper'position to formcontinuations ofthetrack and eliminate the pounding incident tocrossings as at present constructed 5 The invention will be described indetail hereinafter and will be found illustrated in the accompanyingdrawings in which Figure; 1 is a plan'view of'a railway crossing showingthe improvements installed therein,

Figure 2 is a sectionalview on a plane indie cated by the line'2o2 ofFigure 1;

t Figure '3 is'a' similar view on a plane indicated by theline 3'3 ofFigure 1,

' 'Figure4 is atransverse sectionaliview' of one of the tracks on aplane indicated bythe line of Figure '1, and v Figure 5 is a sectionaldetail of one of the movabletread members on a plane indicated by theline 5-5 of Figurel. v

In the drawings similar reference characters are used to designatecorresponding parts in all of the views.

Theinvention is shown applied to a railway crossing having a track Athat is crossed by a track B, the rails 1 of tracks A and B being shownsupported onsleepers 2, and spaced as shown at 3 where the rails of thetracks A and B cross. Mounted in each of the spaces ect of thetinvention" is the ONE-SIXTH To; EOLABARRETT, BOTH on GEORGETOWN; Louisana; Ann 01\TE- 3 is aftread member consisting of; a block 4 having astem 5, that is 'rotatably mounted in the supporting'sleeper 2, ,6indicatingan anti-friotion bearing for the tread member 4. As shown inFigure lithe tread members 4are positioned to form continuations of therails 1 of the track B. When so po itioned it will B will traverse thecrossing withoutany ap preciable knock as the-tread' blocks 4formcontinuations of the railslto carry thewheels froinonesectionofthevrail, to the other in making the crossing.- By moving the'treadblocks 4 through an arc of ninety-jdegreesin each instance it will beapparent that said blocks 4 will then form continuationsi 'ofthe.

track A may traversethe crossing with no perceptible knock} as theblocks 14 v will i formcontinuation-sof the sections of the; railsil oftrack A. The invention'includes means for be apparent that rollingstockon the track o I rails 1,ofthe track A :and rolling stock onmovingthe tread blocks 4 into either ofth Y positions just described,and said movement isqcaused by wheels of the rolling stock ap pl-oachingthe crossing, d h s, mechanism Q 'd scribed.; 1

t :7 indicates a shaft that :is terminally jour i 'naled' in oppositelydisposedsleepers Zin the I crossing, and is provided vwith crank arms 8f extending upwardly and downwardly from the shaft, and said, crank arms8 areconnectv ed: by means of'linlrs with thetread members 4 so thatwhen the shaft 7 is turned through a limited are that is-predetermined"by the length of the crank'arms' 8, the tread blocks 4 willbemovedthrough-an arcof degrees as hereinbefore described toformcontinuations of either of the tracks A ortB as may be necessary to useof the crossing by;

rolling stock on either of thetracks 10in dicates shafts that areterminally journaled in sleepers 2 supporting the rails 1 of track A;remote from the crossing designated C and havingcrank arms 11 that'areconnected by means of rods 12 with crank arms 13. tha't extend above andbelow the shaft 7 so that when the shafts 10 are turned by theinstrumentalities to be hereinafterdescribed the shaft? will be rotatedtoil-move the tread blocks 4' from; the 'position in which they areshown blocks 4 with rails 1 of the track A for the the purposehereinbefore described. 14 indicates another crank arm on each of theshafts 10 and arranged adjacent one of the tracks 1 so that it may beengaged by wheels of rolling stock on track A and by depressing thecrank arm 14 rotate the shaft 10 through the restricted arc to performthe operation hereinbefore described. 15 indicates another shaft that isterminally journaled in the crossing C on the sleepers 2 supporting therails 1 of track B. 16 indicates shafts terminally journaled in sleepers2 of track B remote from the crossingO and having crank arms 17 thereonthat are connectedby means of rods 18 with crank arms 19 on said shaft15, said shafts 16 being actuated by the wheels of rolling stock ontrack Bv engaging a crank arm 20 on shaft 16. As the shafts-7 and 15are'actuated by different instrumentalities, and it is necessary thatthe shaft 7 be actuated by shaft 15 when either shaft 16 is actuated bywheels of rolling stock on track B, and that shaft 15 be actuated whenshaft 7 is turned by the turning movement of shaft 10 by rolling stockon track A, this is accomplished by providing a lateral crank arm 21 onshaft 7, and a crossed lateral crank arm 22 on shaft 15 that contactwith one another when either shaft is'actuated to move thetread blocks 4and to properly position the operative structure in the other track sothat the tread blocks may be returned when the crossing is approached byrolling stock on that track.

In Figures 2 and 3 is shown a hood member 23 that covers the crossing Cand the mechanism therein to protect the mechanism from the weather andalso from gravel, dirt, trash, etc., said hood 23 being secured in anysuit able manner. V Shown in broken lines in Figure 1 are other hoods 24that are designed to protect the shafts 10 and 16, respectively, saidhoods 24: being provided with slots 25, the arms 11 and 17 and saidhoods are secured in any suitable manner such as suggested in Figures 2and 3 to cross pieces 26 connecting the sleepers 2.

hat is claimed is 1. In a railroad crossing having crossed tracks, therails forming the tracks being spaced where crossed, tread membersournaled in said spaces and adapted to complete the tread of either ofthe crossed rails, a shaft suitably ournaled, crank arms on said shaft,links connecting said crank arms and the tread members, and meansactuated by the wheels of rolling stock on the tracks to actuate saidshaft to properly position the tread members to form continuations ofthe rails on which the rolling stock is mounted.

2. In a railroad crossing having crossed.

tracks, rails forming the tracks being spaced where crossed,tr eadmembers Journaled in said spaces and adapted to complete the treads ofeither of the crossed rails, shafts transversely arranged in thecrossing, means connecting said shafts for simultaneous movement, meansactuated by said shafts to rotate said tread members, othershaftsjournaled transversely of the crossed tracks remote from the crossingand connected for simultaneous actuation with said first mentionedshafts, andcrank arms on said other shafts and engageable by the wheelsof rolling stock on the tracks to actuate the shafts. 3. Ina railroadcrossing, rails of crossed tracks having spaces formed therein wherecrossed, tread members mounted for rotation in said spaces and adaptedto complete the treadsiof the crossed tracks selectively, shaftstransversely arranged in the crossing and having their axes crossed,means connecting said shafts for simultaneous rotation, means connectingone of said shafts with the tread members to actuate them, other shaftsjournaled transversely of the crossed tracks and substantially parallelwith one or the other of said crossed tracks, means connecting saidother shaft-s with the crossed shaft parallel thereto for simultaneousrotation, and crank arms on said other shafts and engageable by thewheels of rolling stock on the tracks to actuate the respective shafts.

4. In a railroad crossing, rails of crossed tracks having spaces formedtherein where crossed, tread .members mounted for rotation in saidspaces and adapted to complete the treads of the crossed tracksselectively, shafts journaled in the crossing, the axes of said shaftsbeing crossed, crank arms on said shafts, links connecting the treadmembers with'crank arms on one of said shafts, other shafts journaledtransversely :of the crossed tracks and remote from the crossing, acrank arm on each of said other shafts, rods connecting the lastmentioned crank arms with crank arms on the crossed shafts, a secondcrank arm on each of said other shafts and arranged for engagement bythe wheels of rolling stock on the tracks to rotate the shafts,

and other crank arms on said crossed shafts arranged for engagement withone another to actuate the crossed shafts simultaneously when one of theshafts is actuated;
